AIR GAP (AT FLYWHEEL)
Measure the air gap between of the ignition and
flywheel by thickness gauge.

IGNITION COIL RESISTANCE
1. Measure the resistance of the primary coil by
attaching one ohm-meter lead to the ignition
coil’s primary lead while touching the other test
lead to the iron core.
2. Measure the resistance of the secondary side
of the coil by removing the spark plug cap and
touching one test lead to the spark plug lead
wire while touching the other test lead to the
iron core.
Note:
A false reading will result if the spark plug
cap is not removed.
If the resistance is not as specified, replace the
ignition coil.
SPARK PLUG CAP
Measure the resistance of the spark plug cap by
attaching an ohmmeter.
If the resistance is not as specified, replace the
spark plug cap.
